Hi everyone, I'm stuck with this wire, someone help me.

98 civic ek9 D15B OBD2a

I have searched in other posts but it lacks information

the wire that is marked in yellow




I read pin "D11" is sensor ground but, where the wire is connected exactly, since in my harness it was cut and the wire was hanging

Does it go to a connector with other grounds?

 

hi,
im working on a tps indicator by arduino, so i found this color wire on tps plug too, and found on the ecu too. According to the repair manual it is the SG2 wire, i thing SG=sensor ground. So it is the negative side of the iat’s thermo resistor and the tps potmeter.

Ecu plug
